I've bought myself some rad guards, same ones as yours - I've fitted the guard to the oil cooler but not sure how to secure the radiator ones - How did you secure yours ???
Got mine from trackdaytyres on ebay. They came with instructions & the bits for fittings.
Basically the oil cooler guard is tie-wrapped in two places at either end, the water radiator guards are tucked behind the centre fairing upright thingy then held on with stainless steel lock wire at the other end in two places mate.
